3 Description

The ESD652-Q1 is a bidirectional ESD protection

diode for battery management systems and other

automotive applications. The ESD652-Q1 is rated

to dissipate ESD strikes beyond the maximum level

specified in the IEC 61000-4-2 international standard

(±30kV Contact, ±30kV Air-gap). The device can

clamp 8/20μs surges with peak pulse currents up to

5.5A in accordance with the IEC 61000-4-5 standard.

This device features a 4pF (typical) IO capacitance

enabling high-speed interface protection. The low

dynamic resistance and low clamping voltage help

protect systems against transient events. This

protection is key as automotive systems require a

high level of robustness and reliability when they

control safety devices.

The ESD652-Q1 is available in a small leaded

SOT-23 (DBZ) package.
